Title: Improvements in devices for measuring and indicating fluid pressures
IPC: G01L7/16
Filed: 1936-01-23
Abstract: 468,857. Piston-and-spring pressure gauges. OKILL, J., and TATE, J. R. Jan. 23, 1936, No. 2110. [Class 106 (ii)] In a pressure gauge of the type in which a piston floats between the fluid whose pressure is to be measured and an adjustable compression spring, for instance, as described in Specification 351,003, the spring is interposed between the piston and a non-rotatable, axiallyadjustable pressure block whereby adjustment can be effected without twisting the spring. A spigot member 22, Fig. 1, is adapted to be 'fitted to an indicator cock and carries a piston 46 which is subjected to the pressure to be measured. A counterbalancing spring 39 bears on the piston through the medium of a ball 43 and is held at its upper end by a block 37 which is prevented from rotation by a key 3 7 a, Fig. 4, sliding in a keyway and attached to the block 37 by screws 37c, which screws also carry a rack 65 to drive a pinion 67 and pointer 73 to indicate on a scale 69. The block 37 is raised and lowered by a screw 25 prevented from axial movement by a collar 31 running on a ball bearing and by the hub of a hand wheel 35 which also carries a scale 76 reading against a fixed pointer. The lower end of the traversing screw 25 serves as a stop for the piston 46. A spring-controlled magnifying lever 62 indicates small movements of the piston. In an alternative form, a counter geared to the hand wheel indicates the pressure. To allow for rotatably adjusting the instrument for better observation, the casing is, in a modification, connected by a flange and nut 95, Fig. 9, to a spigot 26a screwed for engagement with the indicator cock.

Title: Improvements in and relating to dishwashing machines
IPC: A47L15/06
Filed: 1950-01-30
Abstract: 667,000. Centrifugal pumps. BRITISH THOMSON-HOUSTON, CO., Ltd. Jan. 30, 1950. [Feb. 9, 1949] No. 2386/50. Class 110(i) [Also in Group XXIII] Relates to a centrifugal pump for discharging water from the washing tub of a dishwashing machine (see Group XXIII). As shown in Fig. 2 the pump comprises a chamber 44 having a discharge opening connected to a hose 48, impeller 47 driven by a motor 27 which also drives the coaxially mounted washing liquid circulating impeller 52, and a cover 102, Fig. 10. The cover has a central sump 117 at the centre of which is an upwardly extending wall 118. Extending tangentially from the wall to the periphery of the cover are vanes 120, 121 which are approximately the height of the wall. In the cover portion between the vanes 120, 121 is provided an arcuate inlet port 122 at the base of the wall 118. In the space between vane 121 and a third vane 123 no port is provided since this space is situated over the discharge or high pressure area of the pump chamber. The vane 123 terminates short of the wall 118 to provide a water flow passage 124 into the. cover area between vanes 123, 120 which area is provided with another port 125 communicating with the pump chamber. Both port slots 122, 125 are therefore in the low pressure area of the pump farthest removed from the discharge port. The port slot size is such that water can drain rapidly therethrough but prevents objects which might damage the pump from entering the chamber. This arrangement of the pump inlet ports prevents splashing and noise which would normally occur if the inlet ports were near to the discharge port. Also the vanes nullify the natural vortex action of water entering the pump chamber.

Abstract: 491,056. Altering physical structure. UMLAUF, A. Jan. 26, 1938, Nos. 2504 and 2505. Convention dates, Aug. 25, 1937 and Dec. 20, 1937. [Classes 83 (ii) and 83 (iv)] Constructional members in the form of metal bars have the yield point increased by twisting the bars cold so as to stretch them beyond the elastic limit and then, still in the cold, untwisting the bars by reversing the direction of rotation while simultaneously applying an axially directed pulling force. An I-section bar 1 may be twisted as shown in Fig. 2 by gripping the ends in chucks and rotating one of the chucks whilst maintaining them at the same distance apart so as to preserve the original length l of the bar. The other chuck is then rotated in the opposite direction and moved away from the first chuck so to produce a straight bar 2, Fig. 4, of an increased length #<l>. Alternatively the bar may first be twisted without axial tension so as to decrease its length by #<l1>, Fig. 9, and then untwisted with axial tension so as to resore it to the original length l<1> or to a greater length. The stretched bars may be used in pure steel construction or as reinforcement for concrete, and for the latter purpose the process may be applied to pairs of round rods as shown in Fig. 7, in which case the rods may be given a further stretch-twisting operation to leave them in a twisted condition with a further increased yield point. The first stretch-twisting operation may also include additional stretching which may be effected prior to, during or after the stretch-twisting, and the process may be applied to bars of T, angle, channel or other section.

Abstract: 620,912. Wrapping-up. DUNLOP RUBBER CO., Ltd., HOGG, W. H., and GRAY, T. E. H. Jan. 31, 1947, No. 2974. [Class 94(i)] A method of packaging articles comprises positioning an article, e.g. a golf ball 1, between sheets 2, 3 of extensible thermoplastic material which heats under the action of a high-frequency electric field, e.g. plasticized polyvinyl chloride, a mixed polymer of vinyl acetate and vinyl chloride or a polyvinyl-butyral, stretching said sheets around the article until their faces contact along an endless line surrounding the article, and sealing the contacting portions together by heating them, as stated, under pressure. A thread or wire may be inserted between the article and the thermoplastic material so as to remove the said material easily, tabs being then formed in the sealed joint. In the form shown, an apparatus comprises two members 4 of e.g. brass and 11 of insulating material having cavities 5, 12 and electrode projections 7, 15, said members 4, 11 when brought together forming a chamber to receive the article to be wrapped. Sheets of thermoplastic material are held across each cavity by clamping plates 17. The members are caused to contact one another' by lowering a rack, connected by a stud 28 to the member 11, through the rotation of a pinion by means of a handle, whereupon the highfrequency electric field is applied to fuse the contacting portions of the material. The spring 22 ensures uniform pressure at all points of contact. The clamp plate 17 is then released from the upper member 11 which is raised, the lower clamp plate 17 is afterwards removed and finally the wrapped ball. The surplus sheet material may be trimmed off by providing one member with a knife surrounding the conductive surface adapted to bear on the other member when the members are pressed together. The packaging can be made a continuous process. According to the Provisional Specification the' lower member may be of frustoconical shape and the upper member is made of wood. Furthermore, the heating of the contacting edges may also be effected by conduction of heat from one or both of the pressure' members, e.g. the lower member may be heated from a resistance element located in or encircling it. The thermoplastic material may then have a basis of e.g. polyethylene, gutta percha or unvulcanized rubber.
